Introduction

Cowork is Anthropic's AI agent for knowledge work. Think of it as Claude Code for everything else. It works autonomously with your computer, local files, and applications to accomplish complex tasks.

This guide walks you through the easiest and most secure way to connect your Langbase account to Cowork via Composio Connect, enabling it to chunk a long document for semantic search, list all conversation threads for this agent, create a new memory for session data, and more such actions on your behalf without compromising your account security.

Also integrate Langbase with

Connecting Langbase to Claude Cowork

1. Open Customize

4. Connect your Langbase account

Back in Cowork, ask the agent to connect to Langbase or give it any Langbase-related task.

For example, ask Cowork to:

  • "Chunk a long document for semantic search"
  • "List all conversation threads for this agent"
  • "Create a new memory for session data"

It will prompt you to authenticate and authorize access.

That's it. Composio's tools are now available in Cowork, and your Langbase account is ready to use.

What is Claude Cowork?

Claude Cowork is Anthropic's agent for general knowledge work. It can use your computer, files, and connected applications to complete longer-running tasks across your work tools.

With Composio Connect, Cowork can securely access apps like Langbase through MCP without you sharing account credentials directly with the agent.

What is the Langbase MCP server, and what's possible with it?

The Langbase MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your Langbase account. It provides structured and secure access to your Langbase projects, letting your agent split content, manage memories, orchestrate threads, and build complex AI data flows on your behalf.

  • Content chunking and processing: Automatically split large documents or text into manageable chunks for downstream processing and efficient AI handling.
  • Memory management: Create, list, or delete memory objects so your agent can organize and retrieve contextual information as needed.
  • Conversation thread orchestration: Start new conversation threads, fetch thread details, or list messages—making it easy for your agent to manage dialogue history and context.
  • Pipe creation and listing: Let your agent create new processing pipes or retrieve all existing pipes, enabling seamless orchestration of data and AI workflows.
  • Document and data retrieval: List all documents stored in a memory, giving your agent access to relevant information and knowledge for any task.

FAQ

What are the differences in Tool Router MCP and Langbase MCP?

With a standalone Langbase MCP server, the agents and LLMs can only access a fixed set of Langbase tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Langbase and many other apps based on the task at hand, all through a single MCP endpoint.

Can I use Tool Router MCP with Claude Cowork?

Yes, you can. Claude Cowork fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right Langbase tools.

Can I manage the permissions and scopes for Langbase while using Tool Router?

Yes, absolutely. You can configure which Langbase scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your Langbase data and credentials are handled as safely as possible.
